Concerto Manykinds
A Rails Engine for displaying multiple types of content in the same template field in Concerto.
To use this engine, add the following to the Concerto Gemfile-plugins, or use the UI to add the plugin:
gem 'concerto_manykinds'
You probably don't need to create the migrations manually with this method shown below, because when you restart Concerto it will automatically run the migrations.
rails generate concerto_manykinds
Then go into the templates you want to modify and add the additional kinds in the sidebar.
